Why do gases always tend to be less soluble in liquids as the temperature is raised ?

Text Solution

Verified by Experts

Mostly dissolution of gasesous in liquid is an exothermic process. It is because the fact that this process involves decrease of entropy. Thus, increase of temperature tends to push the equilibrium towards backward diraction as a result of which solubility of the gas decrease with rise in temperature.
